<p><a name=jaggedlines>:</a><b>jagged lines</b> A pattern constructed by Dean Hickerson in May 2005 that
uses <a href="lex_p.htm#puffer">puffers</a> to produce a line of <a href="lex_b.htm#biblock">bi-blocks</a> that weaves back and
forth in a complicated way.
<p><a name=jam>:</a><b>jam</b> (p3) Found by Achim Flammenkamp in 1988, but not widely known
about until its independent discovery (and naming) by Dean Hickerson
in September 1989. Compare with <a href="lex_m.htm#mold">mold</a>. In fact this is really very
like <a href="lex_c.htm#caterer">caterer</a>. In terms of its 7x7 <a href="lex_b.htm#boundingbox">bounding box</a> it ties with

<p><a name=jaws>:</a><b>Jaws</b> A <a href="lex_b.htm#breeder">breeder</a> constructed by Nick Gotts in February 1997. In the
original version Jaws had an initial <a href="lex_p.htm#population">population</a> of 150, which at
the time was the smallest for any known pattern with superlinear
growth. In November 1997 Gotts produced a 130-cell Jaws using
some <a href="lex_s.htm#switchengine">switch engine</a> <a href="lex_p.htm#predecessor">predecessors</a> found by Paul Callahan. Jaws
has since been beaten by the even smaller <a href="lex_m.htm#mosquito">mosquitoes</a>, <a href="lex_t.htm#teeth">teeth</a>,
<a href="lex_c.htm#catacryst">catacryst</a> and <a href="lex_m.htm#metacatacryst">metacatacryst</a>.
<p>Jaws consists of eight pairs of switch engines which produce a
new block-laying switch engine (plus masses of junk) every 10752
generations. It is therefore an MMS breeder.
<p><a name=jc>:</a><b>JC</b> = <a href="lex_d.htm#deadsparkcoil">dead spark coil</a>
<p><a name=jhc>:</a><b>JHC</b> John Horton Conway. Also another name for <a href="lex_m.htm#monogram">monogram</a>.

Found by Robert Wainwright in November 1984 and named by Bill
Gosper. A p9 version using <a href="lex_s.htm#snacker">snackers</a> instead of pentadecathlons
is also possible.
